Digital signal processing means useful in control of servo loops is disclosed. The servo loop is designed to interface with a microprocessor controlling the loop. In a preferred embodiment, in which the servo loop controls the motion of a read/write head with respect to a magnetic disk, plural previous control signals and output response signals are recursively summed to generate each next position signal. Coefficients for weighting the previous control and response signals are stored in a read only memory accessed by portions of the control and response signals.
